Doesn't have to be your favorites. Could be any group!
I think progressive rock, folk, country, reggae, and jazz for all groups.
Folk and country might seem like bizarre ideas, but Blackpink incorporated that into their song "Stay." Progressive rock may sound wild, but BIGBANG did some of that with "Still Life."
K-pop its cool ways of doing things like that. It actually introduces us to new genres and makes us more open-minded. That's what I love about K-pop.
